- Application filed August 24, 1925. Serial No. 52,146.

This invention relates to mechanism for threading washers on upstanding pins supported on a plate, and its special purpose 15 to provide means forplacing convex washers on rows of upstanding pins aflixed to the bottom-plate of a multiple rubber-heel mold. as more particularly hereinafter'set forth.

Fi 10 is a view partly in vertical section show ng the agitator mechanism;

Figs. 11, 12, 13 and 14 are views of other details of the mechanism hereinafter specificall described;

lid gs. 15 to 24 are detail views of the port able washer-threader.

On an elevated base-board 20, I mount a.

standard 21, and on this standard I mount astationary horizontal shaft 22 on which the tumbler-barrel 23 is journaled, this barrel having a closed rear end to which is affixed a worm-gear 24 which is driven by a worm 25, which worm, in turn, is driven, in the present instance, by an electric motor 26 mountedon the base 20. This mechanism serves to rot-ate the tumbler 23 continuously.

The forward open face of the tumbler is covered by a plate 27 which, in the present instance, is made of glass to permit a clear view of the operations taking place behind the glass. Thisglass plate 27 is bolted to a vertical metal plate 28 by means ofbolts 29 and is arranged" to have frictional contact with the front cylindrical'edge ofthe tumbler-barrel. The plate. 28 is rigidly supported on the base 20, and it is provided with a circular hole through which the front end of the tumbler-barrel projects in order to have direct contact with the face of the glass plate. The forward end of the stationary shaft 22 extends through a hole in the glass plate and a nut 30 is tapped onto the end of the shaft for the purpose of holding the glass plate in proper place. A funnel 31 is fasthe others will, fill in succession.

tened to the face of the glass plate and has a tubular extension 32 which passes through v a hole in the glass late for the purpose of delivering the was iers into the tumblerbarrel.

As will be seen particularly in Fig. 7, the.

rotation of the tumbler in the -direction indicated by the arrow delivers the washers 33 7 into an annular channel 34 formed around the right-hand edge of the tumbler-barrel by means of a strip 35 clamped between the glass plate and the metal plate 28. The washers gravitate down this channel 34 into an oblique channel 36 formed by a strip 37 and the upper ends of stri s 38, these strips 38 forming a plurality of Eve vertical chan-' nels 39, the top edges of the stri s 38 being bevelled off downwardly to the le t to permit the washersto roll by gravity past the tops of all the channels except the last one, i. e. the one at the left. All these strips 38 and 37 are clamped between the glass plate and the metal supporting plate 28.

7 The lower end of the channels 39 deliver serve their para lelism. They desirably incline downwardly toward the right-hand, in the same direction as the receiving-channels 39. The lower ends of these channels 40 are temporarily closed by means of a series of fingers 41 which are adapted to be manually moved from operative position at the will of the operator, as more fully hereinafter set forth.v The washers, as they run down the channel 36, drop into the channels 39 and thence into the tubes 40, coming to rest against the stop-fingers 41. When all the channels are filled, the washers stop rolling into the feed-channel 36, but, of course, the tumbler will continue to rotate. The momentum therollingwashers receive in running down the channel 34 will carry them to the far end of the feed-channel 36,

so that the far channel 40 will usually fill before the others; after this channel fills, In the drawings, Fig. 7, the far channel is filled and the next channel is nearly filled. After a previous channel is filled, a washer lodges on the top of the adjacent divisionestrip 38 and thus serves. to guide-the Succeeding washers into the next adjacent channel. In order to give the washers sufiicient gravity momentum to be carried quickly to the far end of the inclined channel 36, I arrange the point of delivery from the tumbler into thechannel 34 as far to the right of the entrance to channel 34 as practicable. To accomplish this, I provide a metal strip 42 and extend it up along the entrance-side of the channel 34, as shown in Fig. The washers roll up the inner face of this strip 42 and drop off its end into the channel 34 at a point far enough up to give the washers the necessary momentum. This strip 42 1s desirably affixed to a strip 43, clamped between the glass and the metal plate 28 and extending around the edge of the tumbler to close the space between the same and the glass sheet. The washers roll along the inside of this strip 43 until they drop off the end of the extension member 42. All the strips 35, 38 and 43 are deslrably affixed to the metal plate 28 and have their front faces smoothed off so that when the glass plate is bolted up it will fit close against the faces of the strips.

To insure against any of the washers sticking or lodging on the way down the inclined distributing-channel 36,1 provide the following dislodging or agitating devices: At the upper end of each of the divisionstrips 38, ll provide a transverse pin 44 which is carried by a bar 45 arranged on the rear side of the supporting-plate 28, the pins working through slots in said plate 28. This bar 45 is rcciprocated endwisely so as to move the pins 44, back and forth, partway across the upper ends of the channels 39. The means for causing this action of the bar 45 consists of a plurality of radial pins or knobs 46 afix'ed to the exterior of the tumbler and arranged'to work against the cam-face 47 of the bar 45. The bar 45 is allixed to the plate 28 by means of screws 48 48 anchored in the plate 28 and working through slots 49 in the bar, a spring 50 being employed to normally hold the bar in its down position to thus hold the pins 44 back, out of the channels 39. The rotation of the tumbler-barrel 23 gives this bar 45 a comparatively rapid movement back and forth, thus keeping the pins 44 moving rapidly back and forlh partially across the channels 39, the location of these pins in the channels being such that as the washers roll across each channel they will strike one of these pins. In this way, lodgment of the washers against the top ends of the'divisionstrips 38 is absolutely prevented. At the far end of the channel 36 there is provided two additional agitator-pins 44 for the purpose of insuring agitation of any washers that might accumulate, in abutting relation in the disfributing-channelfiti. The tumbler-barrel 23 is desirably provided with perforations 51 for the purpose of dischargingthe foreignmatters that might get into the barrel.

For the purpose of a itatingthe washers as the barrel rotates, l esirahly provide the interior of the barrel with a plurality of curved ribs 52 arranged near the forward edge of the barrel in such manner as to assist in not only tumbling the washers about in the barrel but also in causing them to travel toward the front edge of the barrel, whence they are delivered into the distributing-channel hereinbefore described. The washers gravitate into the radial notches 53 formed in the edge of the barrel and thence down between radial ribs 54 affixed to or formed on the edge of the barrel in such position' as to wipe the inner face of the glass plate as the barrel rotates. As the barrel rotates, the washers drop out of the radial channels formed by the ribs 54 into the curved receiving-channel 34, whence they, as described,'roll down into the distributingchannel 36. When convex washers are used, as in the present instance, it is essential that they be delivered into the channel 34with their convex sides facing all in one direction, inwardly in the present instance. "I insure this by so shaping the radial channels between the ribs 54 as to prevent any washer that lodges in the notch 53 from passing down through said channel unless the convex side faces inwardly. This is shown more particularly. in F i 6, which shows the lower washer 33 in position to pass on into the distributing-channel, while the upper washer 33' is turned with the convex side outwardly and therefore'cannot pass down through the channel. For this purpose, the

channel is centrally dished or deepened at 55, so that unless the convex side, of the washer is turned inwardly, the washer cannot fall down through the channel and will therefore be carried up and tumbled back into the barrel. At the proper s ed of rotation of the barrel, enough of t e washers will be turned in the proper direction for delivery to keep practically a continuous supply of washers running into the distributing-channel 36. .For the purpose of insuring the feed of the washers toward the delivery-channels in the edge of the barrel, the interior of the handle tapered backwardly to thus provide an inclined surface extending downwardly and forwardly. lit will be understood that the strip 43, Fig. 7, extends around the edge of the barrel and closes all the delivery-channels therein except that on the ascending side of the barrel, where a sufl'icient number of the channels are left uncovered to permit the washers to roll out into the receiving-channel 34.

The length of the ma azine channels 40 is suchthat when the owermost row of washers rests upon the sto s 41, the topmost washerin each channel Wlll have its 11 per edge about in line with the top edges the division-strips 38, so that the filling of one of the right-hand magazine channels '39 before the others would. not interfere with the I stop-fingers 56 pivotally mounted at a point o for mounting and opleratin lowest row of washers to above the main fingers 41, in such position as to be manually pressed 'into .enga ement vwith the row of washers just above t e'last row, a spring '59 being provided to throw these fingers off the washers as soon as they are manually released. When the attendant desires to level off the last row of washers, he first clamps the semnd-to-the-lastrow of washers by means of the fingers 56,; then he releases fingers 41, thereby permittin drop out o the tubes; then he lets fingers 41 go. back to closing osition; then he releases supplemental ngers 56 and. thereby permits all the columns of washers to' descend until the lowest row, which has been held up. by the temporary fingers 56, falls into abutting relation with the fingers 41.-

l-iny suitable mechanism maiyl be employed t e stopngers 41 and 56. I have s own t e fingers 41 pivoted at-58, a spring 57 being employed for normally forcing these fingers into action and a stop 60 being employed to restrict the outward movement of the upper end of the I plate 61, carrying'the fingers 41. A plate 62 carrying the fingers 56 is pivoted at '63, on

the side wings of plate 61, the aforesaid spring 59 serving to swing the upper end of this late 62 toward the tubes and thus hold the ngers-out of action.

After the washers have been de osited in the main magazine tubes 40 herein fore described, they remain there until they are removed en masse into a'vertical, detachable magazine designated as a whole by thenumoral 64, which consists of a plurality of tubes. 65 equal in number and cross-sectional shape to the tubes 40. They are, like tubes 40, mounted side by side, so that their upper,

open, inlet-ends may be adjusted into alinement with the open, lower ends of the tubes 40, as shown in dotted lines in Figs. 8 and 9. This exact alinement of the tubes is obtained by a plate 66 rigidly supported on a frame member 67 and provided with side flanges 68, forming a trough in which'the lower ends the of the tubes 40 he, the wings 68 being rovided with inwardly-extending pins 69 w ich together with the back late 66 serve to guide and hold the ends oft e tubes '65 in proper position with respect to the main magazine tubes, so that when the stop-fingers 41 are shifted to release position, the washers in the maincolumns will simultaneously drop by gravity into the tubes 65 of the portable ma zine.

a he portable magazine is held up in position to receive washers by the following 7 means: A swin ing yoke 70 is pivotally mounted on a pin 71 supportedby a.frame member 72, the free ends of the yoke being spring 74 will force the pins 75 upwardly withsulficient power to hold the'detachable magazine in position while the washers are transferring themselves into the detachable ma azine. ,When the detachable magazine is filled, the operator releases the stop-fin-v gers 41 to allow them to go into operative position, and then removes the ortable magazine by simply depressing it ar enough to disconnect the upper ends of its tubes from the guide-plate 66-68.

mechanism whereby, manually moving it The detachable magazine provided with along,,over rows of pins in the mold-plate,

the'pins will automatically withdraw the washers, one by one, from the tubes 65. This mechanism is constructed as follows: A tubelike frame 76 is attached to the lower ends of the tubes 65, just in front of the tubes, by means of a series of brackets 78 whose forwardly-projecting horizontal members lie upon the top'face of the tube-frame .7 6 and are pivotall connected thereto by vertical pivots 79. he lower encls of tubes 65 extend down behind the frame 76 and are curved rearwardly, the extreme lower end of each tube being fastened to the forward ends of the arms 80 of a fork which is pivotally mounted on the lower ends of the aforesaid pivots 79, so that each of these forks 80 has a pivotal action on the same axis as the brackets 78. The ends of the forks curve upwardly at their forward pivoted ends, so that the slot or bifurcation forming the forks will present an open arch 81 facing forwardly. p i

The lower end of each of the tubes 65 is normally closed by a spring finger 82 affixed at its upper end to'the tube 65 and having its lower end shouldered to enterthe channel of the tube, at the point where it lit) of the tubes. This finger is rovided with a longitudinal notch 84 and t e lower end of the tube is also notched at 85, these notches being provided for the purpose of permitting the pins on the moldlate to pass through between the arms 0 the fork 80. The frame member 76 is mounted on a pair of runners 86 arranged outside of the lower the lower edges of the runners 86 resting on.

the upper face thereof and the uide-plate 87 running along between two ad acent rows of pins. The guide-plate and the runners will be so .positioned that as the device is moved along the mold-plate, the several rows of pins thereon will pass into the arches 81 and then on out through the rear ends of the forks. As each pin passes along under its tube 65, it will engage in a hole in the washer, as shown particularly in Fig. 23, and snap the same oil the rear end of the tube and fork, the spring 82 yielding sufliciently to permit this to be done. The parts are so constructed that the lowermost washer ineach tube is presented in an inclined position, as shown in Fig. 23, so that the upper end of the pin will engage the hole in the washer, as stated, and thus, as the device moves along, snap the washer away from the spring in the fork; and as each washer .is snapped 0d the next Washer drops into place to be in turn picked off by the next pin in that row.

For one reason or another, the pins in the mold-plate are not always in exact alinement, hence it is desirable that means he provided whereby the washer-delivering devices shall be capable of automatic lateral adjustment. This is providedfor by the pivoting of the forks 80 and the brackets 7 8 on the frame, by means of the pivots 7 9. lVith this pivotal arrangement, it will be seen that when thefork 80 encounters a pm slightly bent or out of alinement to the remaining pins, the fork may yield laterally, in either direction, to accommodate such pin. The tubesare connected together at their upper .ends by a cross-bar or plate 88. This does not hinder the'proper operation of these pivotal connections, as the tubes are of sufficiently thin metal and of sutlicient length to yield torsionally to a sutlicient degree to permit the comparatively slight lateral movements of the forks that are required.

A guard plate 89 is positioned to the rear and just above the rear ends of the delivery forks 80, this guard plate being supported by means of arms 90 attached to the frame 76, in position to pass just over the top ends of the mold-pins. The object of this is to prevent the washers jouncing off the pins. after they are placed thereon. As the device moves along, the guard plate passes over the top ends of the transverse row of pins immediately after the washers are deposited thereon, thus preventing the washers flopping olf the pins, thereby enabling the operator to niovethe threading apparatus across the mold-plate with considerable speed.

It is desirable that the runners 86 shall be vertically adjustable with reference to the frame member 76 in order that the apparatus may be adapted for mold-pins of different heights. ll accomplish this adjustment in the following manner: Attached to the runners and rigidly connecting them is a yoke 91 which lies within the tubular' frame 76 and is connected with the top wall thereof by means of a clamp screw 92, whose upper threaded end extends up through a slot 93 in the top wall of the frame member, a clamp-nut 94 being provided to draw the yoke-member and the adjacent wall of the frame toward each other. By tightening the thumb-nut 942, it will be seen that the frame member is clamped hard against the upper edges of the runners, thus providing for a rigid frame structure. The upper edges of the runners enter transverse slits 95 formed in the frame member and the upper edges of the runners are each provided with a pair of stepped abutments 96. In Fig. 21, the adjustment is the lowest obtainable with the present construction. For longer moldpins, the thumb-nut 94 will be loosened and the runners will be adjusted to bring into use higher pairs of steps 96.

As will be seen from Fig. 18, the lefthand one of the tubes 65 is in reality a supplemental tube in that it is so constructed as to deliver its charge of washers into the adjacent one of the tubes, the lower end of the channel, at 97 being turned downwardly and merged with the channel of the adjacent tube. The purpose of this supplemental tube is to supply an extra number of washers to said adjacent tube. The need for this is due to the fact that in the heel molds now in general use, one row of the pins contains more pins than the other rows, thereby necessitating a larger number of washers for the tube that supplies that row of pins. In use of the device, when the washers in the main tube are discharged to a point below the junction with the supplemental tube, the attendant brings the supplemental tube into communication with its adjacent tube by swinging over a little gate 98 pivoted at the junction of the chann'els are Bill) mental tube to gravitate into the main tube.

This gate 98 is mounted on a plate 99 pivotally supported at 100 so that the to.

may be shifted to either position by e gewisely moving the lower end of the plate 99. This plate is desirably made of glass to permit the attendant to watch the movement of the washers in the channel. The gate-carrying plate 99 'is limited in its movements by means of a bolt 101 mounted on a plate or bar connecting the two -adja-' cent tubes, the plate 99 being provided with a slot 102 to permit limited movement of the plate. The pivot 100 is mounted on a bar 103 which connects the supplemental tube to its main tube. The plate 88 heretofore described also connects the supplemental tube with its main tube. This plate 88 is slightly resilient to form a sort of pivotal connection between the two left side tubes and the remainder of the bank of tubes, this being desirable in order to facilitate the pivotal action of'the fork 80 which is connected tothis pair of tubes.

I have shown the base 20 supported on a tripod frameand the-magazine support consists of a tubular rod depending from the upper end of said franc. This frame arrangement is merel for illustrative purposes, it being obvious that any suitable arrangement of frame structure .may be employed. In fact, it may be desirable in someinstances to mount the apparatus on a trolley line so that it may be shifted about from one set of molds to another set. The rapidity with which the main magazine is refilled and the quickness and ease with which a charge of washers may be transferred to the portable magazine renders it possible for this apparatus to be usedto supply a large number of molds, hence, as stated, it ma be desirable in some instances to provi e-means for readily shifting the apparatus from point to point in the sho in order to reduce the time of the atten ant in getting the portable-magazine recharged. I have shown a swinging trough 104 normally suspended underneath the main magazine tubes 40 to catch any washers that may fall out of the tubes when the portable maga zine tube 65 is not in osition. This trough is so supported that w en the portable tubes are put in position, the trough will'be thereby moved to one side out of the way. A bucket 105 may be supported at the deliveryend of the trough to receive the washers that drop into the trough.

It is obvious, that in some case I may do away with the set of magazine tubes 40 and deliver the washers directly into the ortable magazine from the channels 39; in t 'is case,

however, it will of course be necessary to leave/the portable magazine attached a sufiic'ient length of time to permit the washers feed sing y-into the tubes 65, iust as the run into the channels 39.
